人教版新課標高中物理必修2行星的運動說課稿
一、教材分析行星的運動選自人教版普通高中物理必修2第六章第1節(jié)。本節(jié)教學既是前面《運動的描述》和《曲線運動》內容的進一步的延伸和拓展，又能為后面學習萬有引力定律做鋪墊。在本章中占有較為重要的地位，具有承前啟后的作用。同時該節(jié)內容也涉及大量物理史實、貼近學生生活和聯(lián)系社會實際的事實，可進一步培育學生的科學情感、精神和發(fā)展觀。（一）教學目標 1．知識與技能（1）知道地心說和日心說的基本內容。（2.）掌握理解開普勒三大定律的內容，并能應用。（3）理解人們對行星運動的認識過程是漫長復雜的，真理是來之不易的。2．過程與方法通過托勒密、哥白尼、第谷·布拉赫、開普勒等幾位科學家對行星運動的不同認識，了解人類認識事物本質的曲折性并加深對行星運動的理解。3．情感、態(tài)度與價值觀（1）澄清對天體運動神秘、模糊的認識，掌握人類認識自然規(guī)律的科學方法。（2）感悟科學是人類進步不竭的動力。
人教版高中地理必修2第六章第二節(jié)中國的可持續(xù)發(fā)展實踐說課稿
1．導入新課：用觸目精心的一首MTV《EARTHSONG》導入新課，引出人類已經面臨嚴峻的人口、資源與環(huán)境的危機。而中國是世界上人口最龐大的國家，人口、資源與環(huán)境問題更加嚴重。既然我們知道了可持續(xù)發(fā)展的概況，了解了它的發(fā)展過程，從上節(jié)課內容的分析中，也理解了作為人類的發(fā)展，可持續(xù)是唯一的選擇，也是我們所追求的目標，那么，具體到我們國家、我們周圍的生產、生活情況又該如何呢?2.新課講授：首先，通過三則補充材料的案例和課本上的內容分別說明龐大的人口壓力，資源短缺和不合理利用，深刻的環(huán)境危機方面的問題，得出走可持續(xù)發(fā)展之路是我國的必然的唯一的選擇。接著通過《中國21世紀議程》——中國21世紀人口環(huán)境與發(fā)展的白皮書的過渡引出實施可持續(xù)發(fā)展的途徑。在這部分內容的講解上，主要通過其中一種主要途徑-循環(huán)經濟的講解，特別是對清潔生產和生態(tài)農業(yè)的具體分析，總結出中國走可持續(xù)發(fā)展之路事在必行，行必有果。再通過完成課本上最后一個活動題對本節(jié)內容進行深化。
人教版高中生物必修2伴性遺傳說課稿
（1觀察圖解，色盲基因在性別間是如何傳遞的呢？（女--女、女--男、男--女）（2）為什么不能由男性傳給男性？（色盲基因是在X染色體上，因此色盲基因是隨X染色體的傳遞而傳遞。）（3）男性的色盲基因怎樣才能傳給男性呢？（通過女兒，傳給外孫即交叉遺傳）（4）從圖解看色盲在男女中的發(fā)病情況怎樣？（男性多于女性）（5）從社會調查也是這樣，你是否能從基因和染色體的角度加以解釋？（提示：女性染色體的構成，結合基因位置及顯隱性進行分析）歸納特點：歸納出色盲基因遺傳的特點并擴展到X染色體隱性遺傳的特點上。色盲基因遺傳（X隱性遺傳）的特點：（1）男患者多于女患者（2）交叉遺傳（3）女病兒子必病，男正女兒必正等。問題探討：利用“遺傳圖解”結合“問題鏈”繼續(xù)探討，拓展到抗維生素D即X 染色體顯性遺傳的特點。（6）色盲基因在X染色體上屬隱性基因，子代表現(xiàn)男多于女，對應的正常色覺基因則屬于X顯性基因，子代表現(xiàn)應如何？（女多于男）
人教版高中生物必修2基因在染色體上說課稿
三、孟德爾遺傳規(guī)律的現(xiàn)代解釋①分離定律：在雜合體的細胞中，位于一對同源染色體上的等位基因，具有一定的獨立性；在減數(shù)分裂形成配子的過程中，等位基因隨同源染色體的分開而分離，獨立地隨配子遺傳給后代。②自由組合定律：位于非同源染色體上的非等位基因的分離或組合是互不干擾的；在減數(shù)分裂過程中，同源染色體的等位基因彼此分離的同時，非同源染色體上的非等位基因自由組合?？偨Y：再次強調孟德爾遺傳定律的現(xiàn)代解釋課堂練習：書本31頁6、教學反思：本節(jié)課設置了一系列問題情境，層層設問，在學生答問、質疑、討論過程中讓學生建構新概念和新的知識體系，并通過教師及時掌握反饋信息，適時點撥、調節(jié)，讓學生在推理判斷中培養(yǎng)良好的思維習慣和對知識的遷移能力，而且通過留出一定的時間讓學生提問，體現(xiàn)了以學生為主體的思想。
人教版高中生物必修2染色體變異說課稿
四、說教學程序（一）.溫故知新、導入新課復習提問:基因突變導致生物變異的原因是什么?回答:基因突變是基因結構發(fā)生改變，從而使遺傳信息改變，使蛋白質結構改變、生物性狀改變，即生物發(fā)生了變異。那么，基因是什么?它和染色體又有何關系?回答:基因是有遺傳效應的DNA片斷，染色體是DNA的載體，基因在染色體上呈線形排列。引出新知:對于一個生物體來說，正常情況下，其染色體的結構和數(shù)量都是穩(wěn)定的。但在自然條件或人為因素的影響下，染色體的結構和數(shù)量均會發(fā)生改變，從而導致生物性狀的改變，這就屬于染色體變異。（二）.把握重點、突破難點重點的把握：1、染色體結構的變異播放影片:貓叫綜合征幼兒。讓學生觀察: 患兒哭聲輕、音調高，很像貓叫。教師補充: 患兒的征狀---兩眼較低、耳位低下，存在著嚴重的智力障礙。闡述病因---染色體片段缺失
人教版高中地理必修2綠色產品知多少說課稿
各小組派代表匯報。4、教師提出問題組織學生討論：⑴要想了解更多的綠色食品，了解綠色食品的銷售情況，我們應該怎么做？⑵要想了解廣大消費者對綠色食品的態(tài)度，食用綠色食品的意義，是否懂得辨認綠色食品，以及什么樣的人群對此知識最缺乏等，我們應該怎么做？組織學生匯報交流。5、做個“綠色食品”廣告設計師。為你喜歡的綠色食品設計廣告語，每組推薦一個。6、讓學生了解綠色食品認證程序。7、綠色食品打“假”隊員在行動。8、向學生介紹生態(tài)綠色食品基地。三、活動總結：通過研究、探討，了解學生對綠色食品的態(tài)度。提問：民以食為天，吃，是一個大問題，如果你的爸爸媽媽讓你到超市買牛奶、方便面等，你會選擇什么樣的食品？為什么？希望通過今天的學習，同學們能夠做到綠色消費，也希望你們向自己的家人、向周圍的了解學生對“無公害食品”、“有機食品”與“綠色食品”的認識。
人教版高中地理必修2煤城焦作出路何在說課稿
分析過焦作市的地理概況和產業(yè)優(yōu)勢后，就需要針對由于資源枯竭所帶來的問題提出合理化的建議。既然是談經濟轉型，就應該將話題的范圍明確在這一領域內。通過材料3的相關內容，我們了解到焦作市需要在產業(yè)結構調整、培育新的優(yōu)勢產業(yè)、增強綜合競爭力等三個整改方針上下功夫。因而引導學生針對優(yōu)勢與不足提出建議，以三個整改方針為基準，衡量建議的可行性是鍛煉學生解決此類問題的有效途徑。在此我將教會學生的是解決問題方法而非案例的內容，正所謂“授之以魚，不如授之以漁”。接下來針對學生的建議和教材資料分析所羅列的10點整改思路，由學生自由發(fā)言提出看法，通過教師的指導和學生的討論，進而確定經濟轉型建議的具體方案。最后注意將建議與產業(yè)優(yōu)勢相對照，看建議是否都是圍繞著產業(yè)優(yōu)勢而提出的，這樣做會加深學生的印象，通過建議和優(yōu)勢的對應關系，將不難找出此類問題的解題思路。
人教版高中語文必修3《勸學》說課稿3篇
《勸學》是普通高中課程標準試驗教科書語文必修三第三單元的重點篇目，該文集中反映著名思想家荀子在學習問題上的觀點和精彩斐然的論證藝術。該單元所選課文都是古代的議論性散文。通過本單元的學習在于讓學生感受我國傳統(tǒng)文化的精神，掌握基礎的文言語法知識，學習如何清晰有力的表達自己的思想和見解。本文安排在單元的第一篇，如何指導學生學好這篇課文，是實現(xiàn)“授之以漁”，樹立學生學好文言文的信心，掌握文言學習方法的關鍵。根據(jù)新課標倡導從“知識與能力”、“過程與方法”、“情感態(tài)度與價值觀”三方面出發(fā)設計課程目標的要求和高一的學生對于文言文的知識還在積累的階段，應該注重基礎知識的積累和一定量的誦讀的實際情況。我擬確定以下教學目標：1，了解荀子論述學習的思想，明確學習要靠積累、堅持不懈、專心致志的道理。2，掌握積累文言實詞、虛詞，活用、古今異議等現(xiàn)象和固定句式。
人教版高中語文必修3《祝?！氛f課稿3篇
各位評委老師，大家好。我說課的題目是《祝福》。一、說教材（一）教材所處的位置和地位高中語文新課程教材必修五本書，共有2個單元中外小說單元。一個必修3的第一單元，一個是必修5的第一單元，共六篇文章。（《林黛玉進賈府》《祝?！贰独先伺c海》《林教頭風雪山神廟》《裝在套子里的人》《邊城》）《祝?！肥菍儆谇罢?。小說是擁有眾多讀者的一種文體，它可以多方面刻畫人物性格，描摹人物心理，完整地表現(xiàn)人物之間的沖突，還可以具體生動地再現(xiàn)人物生活的環(huán)境，因此在反映復雜的社會生活方面具有獨特優(yōu)勢。所以學習小說這種文學樣式，也是有助于學生學會鑒賞小說的基本方法，為將來的小說閱讀打下基礎。魯迅的《祝?！肥侵袊F(xiàn)代小說的精品，當中的人物祥林嫂也是魯迅小說中與阿Q、孔乙己三個最為出名的人物之一。研讀好這篇文章，對將來小說的閱讀，小說中人物的理解，甚至小說的寫作都有深廣意義。

Step 2 Pre-listeningAfter students finish their discussion, I will show a picture of Newton and ask them: Who is him? What is he famous for? Could you find out some words to describe him?

人教版高中語文必修3《林黛玉進賈府》說課稿5篇
【教學目標】我設置的本課的教學目標有三個:1、知識與技能(1)了解曹雪芹及《紅樓夢》(2)學習通過一個人物的行蹤、所見所聞,介紹典型環(huán)境,認識封建貴族階級豪奢極恥的生活以及森嚴的等級、禮儀制度(3)分析小說人物出場的描寫藝術，培養(yǎng)學生分析小說人物形象的能力。(4)一葉落而知秋”，通過對“林黛玉進賈府”這一故事情節(jié)的把握是否能引發(fā)對《紅樓夢》的認知興趣，并找到一個突破口，有針對性地進行自主探究，進而進行個性化解讀。（5）整體認知小說,認識小說悲劇的必然性和思想價值.2、過程與方法(1)用直觀演示和歸納探究法分析文章要點。(2)用討論探究法體驗作者對文中人物的情感態(tài)度。3、情感態(tài)度價值觀(1)正確理解《紅樓夢》的思想內涵,培養(yǎng)學生熱愛祖國傳統(tǒng)文化的思想感情。(2)認識封建大家族的腐朽沒落,理解賈寶玉追求個性自由反封建的精神。
人教版高中語文必修3《過秦論》說課稿3篇
本文篇幅較長，并且有一字句不易理解，因而對高一學生來說完全讀懂內容有一些困難。這樣的話，老師就要做好引導工作，把一些難點，或是出現(xiàn)詞類活用比較多，局勢比較特殊的句子，老師可以先給學生畫出來，存疑，或是與同學們一起討論解決。對那些不易懂的字詞就引導學生聯(lián)系上下文提供的語境、前后涉及的情節(jié)加以推測、判斷，以培養(yǎng)學生依據(jù)文脈推斷詞義的好方法。要求學生點出重點實詞、框出通假字，主要是為幫助學生積累和掌握一些文言文中常見的一詞多義、異讀現(xiàn)象、古今異義和通假現(xiàn)象的詞語，并進一步得出規(guī)律，指導今后的文言文學習。詞類活用和特殊句式在文言文翻譯中難度較大，也是本文教學的兩大難點。要求學生標出有活用現(xiàn)象的字和劃出句式特殊的句子，是基于兩點考慮：1、積累一定數(shù)量的第一手例句；2、引導學生加以分類，找出每類的相同特征，并抽取出來形成規(guī)律性的東西，從而上升到理性認識，使學生能由學會一個到會學多個。翻譯過程中注重指導學生養(yǎng)成用符號法表示重點字句的好習慣，如點、框、圈、劃線等符號應約定一致，便于突出翻譯中的重點、難點及復習。我的提示著重歸納了實詞“制”“亡”“遺”“利”等，名詞活用、形容詞活用、使動用法，被動句、狀語后置句。
